| CTTY--Notes |
|
| Setting up a serial port for CTTY |
|
| Use the MODE command to set up your serial port for baud rate, parity, bits, |
| and stop bit before using the CTTY command. |
|
| Using CTTY with programs that do not use MS-DOS |
|
| Many programs do not use MS-DOS for input or output. These programs send |
| input directly to the hardware on your computer. The CTTY command has no |
| effect on these programs; it affects only programs that use MS-DOS for |
| reading keyboard input and displaying output. |
|
| Setting the terminal device with COMMAND |
|
| In addition to the CTTY command, you can use the device parameter of the |
| COMMAND command to specify the input device. |
|
| CTTY--Examples |
|
| To change control of all input and output from the current device (your |
| computer monitor and keyboard) to the AUX port, type the following at the |
| command prompt: |
|
| ctty aux |
|
| In this example, a remote terminal device connected to the AUX port controls |
| input and output for your system. |
|
| To transfer input and output back to the monitor and keyboard, type the |
| following command at the remote terminal: |
|
| ctty con |
|
